Numerische und experimentelle Simulation der Anzündung von Schüttpulverladungen
Abstract
Particular time-dependent features of the ignition process in large caliber tube weapons are studied numerically and experimentally, e.g., the spatial propagation of the flame and of the pressure in the granular charge. The multidimensional code AMI for interior ballistic two-phase flows is applied. The experiments are conducted with a simulator allowing pressure measurements at several locations along the chamber wall as well as in the interior of the charge. By means of the forces aching on the projectile base the grain pressure is evaluated. In order to check how ignition might take a bad turn, irregular ignitor functions are also considered. The results are compared for the charge of a 105-mm tank gun.
